Does anyone else have this problem or is my Delphi cursed somehow?
I'll have a bunch of forms and files open in tabs in the editor and I'll be typing away and then suddenly everything stops - my .pas file has, seemingly at random, become read-only.
Sometimes I can just right-click the tab at the top and uncheck "Read-Only" and continue, but sometimes this option is checked and greyed-out (disabled), meaning I can't uncheck it and I can't make any further edits to the file. This too seems to be random.
In the latter case, the only solution is to save the file in question, which works, despite Delphi's assertion that the file is read-only, close its tab in the editor, and re-open it. Not catastrophic, really, but it's starting to become annoying.
Could it be that I am hitting a keyboard command combination accidentally to do this or is this a bug in Delphi?
I'm in Delphi 2010, Windows 7. Doubt it's anything to do with installed packages, but if anyone wants the list I'll generate it and attach it here.
Skip to last paragraph for quick Solution :)
Yes! this just happened to me. I was typing a line of code... a line in Intraweb's ServerController.... OnBeforeDisbatch.. anyways. I was typing..
If
and then I typed a Space... so If <---- then space... and then the IDE autofilled in
If True then
after the above line was in the system all hell broke loose.... hell being that the file would stay in a read-only mode....
I edited the file manually and removed the line
if True then
and all is good.
just to update: I do believe it is file size... 125K and then bang. at least on the server controller... IW10/Delphi 2010
update again... 8 hours later...
I reduced my source file (iwservercontroller) from 125k to well under 80k and all was good. then now right when I first press the control key to paste over a value the file goes read-only!! like wow....
going to reduce file again..
Minutes later...
after shutting down d2010 and reloading project... I have narrowed down the problem to using the "paste" command.... the second I tried to paste a clipboard value read-only occurred... but a harddrive hit occurred for a instant before the read-only activated!
Final solution!!! I got it! I couldn't believe there is a "Read Only" option in the Right Click Menu.... Click on the left side Pane where the check box is when the Read-Only appears! no more need to restart IDE and reload everything etc etc...
All fixed... whoo hoo
Nope... not all fixed... 3 hours later... I reactivate IDE and I am just about to paste in some data and then the file goes in read only (not explorer's file attributes) and the Pop up menu value is now grayed out!! like wtf!!
Full day later.. trying everything.. I have a solution!! first time I got it to go off read-only without using the PUM/insert Key
simply just access the unit in question that is causing read-only and do a single character change with a outside app. (ultraedit) and save. upon saving d2010 will detect outside changes and go switch back to insert-mode even with the pop up menu is disabled.... whoo hoo...
* Final Solution *
Things are all good now and not a single read-only but the solution is not too elegant in terms of keeping my text edit habits in check.. but if you open settings and change the editor to keep insert mode on you will be laughing to the bank... at least things are all good for me now.
Delphi2010-->Options-->Editor Options-->["Insert Mode"] check that option.
Seems since i have had the above checkbox clicked not a single Read-only.... good luck.
This happened once to me. I think it's a bug, I can't find an existing report for it and when you find repeatable steps the please create QC report for it.
This happens to us all the time - once a file gets over a certain size/complexity Delphi starts randomly going read only - sometimes accompanied by freezing for several seconds.
We think it's something to do with the syntax highlighter failing on certain constructs - certainly it comes and goes in waves, and I've had times where I've been reduced to editing a file in notepad just to get some work done.
It happens on units with no related DFM, so it's not a component doing it, and it's not storage related (Delphi isn't writing to the disk when it fails).
Yes, this just started happening to me after I installed Model Maker 11. I think the Model Maker plug-in might be monkeying around with the read only setting of a source file. (I've been using Delphi 2010 for a year now without this issue ever happening, all of a sudden it started right around the time I got MM11.) I haven't tried uninstalling MM11 yet though. So --- do you have ModelMaker 11?
I've seen it many, many times in Delphi 7 which rules out some of the explanations others have suggested.
I haven't seen it on 2010 but I haven't done all that much with 2010.
I also see a switch to "readonly" for pas files in the D2010 editor. None of the above suggestions have always worked for me. I am transferring a large project from D6 to D2010 and am making many necessary changes. On way to overcome the problem for a file that has been marked "readonly" and where (right-click in the editor "[ ] Read Only") has been greyed out, is to close the file and reopen it.
In a Delphi Project CTRL + Space not working.
Before "uses" when I Press CTRL + Space the code completion is appeared but after "uses" does not appear.
I use Delphi 2009.
I install Fastreport and raize components and vcl Skin.
The most probable cause for your problem is that you have some smal syntactical error like missing semicolom, invalid name, etc. somewhere between the point where CTRL+Space works and where no longer works. This is due the way how Code Insight is checking the code structure.
So I recomend you go to menu Project and then chose Syntax Check.
Another cause for CTRL+Space not working is that your are still debuging your program. Do nte that while debugging sesion is in progress both Code Insight and Error Insight are disabled.
Something that in general wreaks havoc with Code Insight (Ctrl+Space) is conditional compilation.
So watch out for {$IFDEF ...} in your code.
I prefer to avoid conditional compilation in anything except library code that needs to support multiple Delphi versions. However, if you must use it, consider inverting the logic so you can use {$IFNDEF ...}.
Also, the feature doesn't always work if your code cannot compile. This depends on what dependencies are unable to compile at the point where you press Ctrl+Space.
However, in my experience the feature does sometimes just "break". If you're lucky closing and re-opening the project fixes it. But usually I have to close and re-open Delphi and do a full rebuild of the project.
I had the same problem I press Ctrl+Space to all units in uses section and I see one unit Delphi can't recognize. I delete it and type it again with Ctrl+Space; after that everything is ok.
another reason is if exists a special character like a tab character in your unit.
The "So watch out for {$IFDEF ...} in your code." had this. Temporarily did a Ctrl-X on it and then did Ctrl+Spacebar and pasted the code back in. Then... it worked again. Delphi XE10.1 Update 2. Other reasons why it sometimes doesn't work still remain a mystery. Can be very frustrating indeed.
From time to time I lose breakpoint functionality in Delphi.
I thought this to be a Delphi 2009 issue but now I have also it in Delphi XE.
In Delphi 2009 by deleting .dproj file I made the breakpoints work again.
In Delphi XE I am not able to make breakopints appear. I have update 1 with all hotfixes applied.
Does anyone have a solution?
Debug info isn't present in the file.
Make sure that you're using the Debug configuration. (Project Manager tree, expand Build Configurations, make sure Debug is bold. If it's not, right click Debug and choose Activate from the context menu.) Make sure you then do a Build of your project, not just a Compile.
If that still doesn't work, go to Project->Options from the IDE's main menu, click on Compiling under Delphi Compiler, and check the Debugging section on the right half of the window. Make sure that Debug Information and Local Symbols are both checked. If you're trying to trace into the VCL's own source, also check Use debug .dcus (you'll want to turn this off and do a full build of your project as soon as you're done, as it gets annoying when you're debugging normally). Again, you'll want to build and not compile.
If all of the above fails, another possibility is that the code unit you have open in the Code Editor isn't the same one being seen by the compiler. Make sure you don't have multiple copies of the file on your computer in a location that the compiler might find first. If you're not sure, delete the .dcu files with that unit name and then do a build of your project, and see if the newly created .dcu is in the location you'd expect.
I found a better way.
From the Project Manager tree, right click on the project and choose "Clean" from the popupmenu.
The breakpoints reappear magically and it is a very fast method.
I suspect this happens when you have done a release build, with debug disabled. Then you switch back to debug configuration and do a compile rather than a build. The files where you can't set breakpoints correspond to those with DCUs produced by a compile with debug disabled.
Simply doing a build to re-generate all DCU files will make your breakpoints work again.
Here's one more reason to misaligned code vs breakpoint markers (blue/red "pill" in the gutter).
The editor recognices three different line endings,
CRLF (Carriage Return - Line Feed pair)
CR only
LF only
Of these, CRLF is the default in the editor.
The compiler however, doesn't seem to consider CR only as a line ending, only CRLF and LF only. Thus if your source file happens to have one or more CR only, the "blue pills" will be offset from the source.
You might have got source files with CR only EOL (end of line) character from e.g. the internet. I recall MAC OS used CR only as EOL.
To verify the EOL's in your file, you can turn on the displaying of EOL's in the editor
( Tools - Options - Editor options - Source options - Show line breaks).
The symbols look weird (see images below), but are just C on top of L for CRLF, C on top of R for CR and L on top of F for LF.
The following images show the normal EOL's (CRLF) and the EOLS's after I forced CR only for one line and LF only for another line in a hex editor. As said above, it is the CR only that offsets the break point markers from the source code.
Normal CRLF EOL's:
One line with CR only and one with LF only:
Fix
To reset all EOL's to CRLF, untick Preserve line ends in Editor Options
( Tools - Options - Editor options),
make a trivial change, so that the file is marked as modified, close the file, save changes to XYZ.pas? YES, and reopen.
Now all line endings are CRLF. Rebuilt the project and all the breakpoint balls will be in the correct locations.
Turning on remote debugging symbols did it for me (nothing else worked). Project > Options > Linking and check Include remote debug symbols.
I had the same problem with XE4. This is why I found this article a couple of hours ago. None of the above solutions worked for me. The correct solution for me - up to now - was to add "remote debug symbols" option. Strange because I don't use remote debugging. Anyway it looks OK now.
It is a bug, restarting Delphi will fix your problem.
Try remote debugging to your local PC.
Why it works: (source)
When you debug Delphi projects locally, RAD Studio does not use your RSM debug file because the compiler holds the symbol tables in memory. However, when you debug Delphi projects remotely, you must generate an RSM debug file that contains those symbol tables; otherwise, RAD Studio does not stop at your breakpoints.
Of course, you must first configure your project's "Linking" option "Map file" to "Detailed" to generate the *.rsm file. See Overview of Remote Debugging for how to get started.
I had a related problem: I lost the breakpoints in a particular file, but the other files were fine. What had happened was that I had renamed that file, but unknown to me the DCU for the old file was still being used because it was being referenced in a "uses" clause somewhere.
The solution is to manually delete all the DCUs (doing a "clean" is not enough because the old file represented by the DCU is no longer in the project) and rebuild. You will get a compile error showing the bad "uses" clauses.
Another reason for not working breakpoint could be (often tested with delphi5):
Too many procedures in a unit.
The solution is to move procedures to another unit
Although this is an old question I can confirm that this is still an issue in the current version of Delphi 10.3 Rio.
The answer above regarding line endings
https://stackoverflow.com/a/53360447/6445054
Solved the issue for me I had imported some very old Delphi code which had CR line endings
in a couple of places, as soon as I started moving code around the debugging broke completely.
The option to turn line endings on has moved slightly in Rio it's now
( Tools - Options - Editor - Source - Show line breaks).
In delphi 7 there seems to be a real bug on setting breakpoints.
I had a unit where many texts are definied in a
const constname : array[0..x] of record-type = (...);
in interface section, where record-type has some AnsiString items.
In the implementation section there are some procedures.
In some particular cases, when I set a breakpoint anywhere within a procedure, delphi does not stop at it!
Remarks: all options for debugging are set properly (as for F7 causes delphi stop at the "begin" of the program, blue dots are visible in the whole unit the line stays red while executing the app) and all DCUs that have according PAS files were deleted from all of my disks and within all folders, before I did a complete build on the whole project. So no wold files should hang around anywhere.
For testing, I renamed the PAS to another name, never ever used before, and surely nowhere else on any disk, then adapted all sources and recompiled, just to be sure that delphi and I are looking at the same PAS file - but the breakpoints did not work either.
But there another, very weird thing happened: the text consts (!) changed within my executable (not within exe file, but obviously within memory)! Those texts were checked for correctness during program start, and sometimes it complained about errors! Display of the texts in a messagebox showed, that there was changed a sinlge character within that texts, that are defined as const. For test, I tried to assign something to that consts within my code, but, as expected, compiler complained, so it cannot be an ordinary assignment that causes the change of the text. Must be a wrong pointer. Weird.
So, hours of testing followed, looking for any source code that might have set up a wrong pointer that later could cause that change in a text const. I placed the messagebox into the initialization section of the first unit within the chain of unit initialization I was able to edit, but the changed char was already there! Must be changed very early during startup of my application, then!
Finally I figured out, that the char that appeared in my texts always was an $CC - which exactly is the assembler code for INT 3, the code that delphi is using for setting a breakpoint. And when moving a breakpoint within that unit a line up or down, the position of the changed character also moves some chars left or right! And the number of characters the wrong one moved just correlated with the estimated amount of assembler coded bytes the concerned lines needed. Setting two breakpoint in lines near each other, suddenly two characters changed! When removing all breakpoints from that unit, the text remained unchanged!
So there's only one conclusion: delphi itself is changing that texts when trying to set a breakpoint and fails to do so. I was unable to get rid of this bug. None of the tips about re-synching delphi's internal bookkeeping of source and object code files did help me out!
As the concerned unit mainly consisted of {$I} lines between multiple {$IFDEF}s, for including some different, but long pascal texts, I considered delphi having problems on too long inclusions or on evaluation of conditional compiler directives. So I removed the includes and put the source text immediately into the unit, and removed the {$IFDEF}s - which compiled without errors, but setting breakpoints also changed my text constants, instead of stopping execution. All the same!
I solved this for now by splitting the unit into two units, one holding just the text consts in it's interface part, and a second one to hold the procedures. And now, without changing any compiler nor linker settings, all breakpoints do work like expected and not text is changed any more!
So, if breakpoints do not work for you, while you are sure they should, possibly delphi is the culprit and fails to set the breakpoints at the correct place. In case of it is changing just some texts, maybe that never gets to your attention. Splitting the unit helped me out, maybe that helps you, too.
If the file you're trying to set breakpoints in is part of a DLL, you need to make that DLL active by double-clicking on it in Project Manager so it turns bold, and then build it. Then the blue circles will show up next to lines where you're allowed to set breakpoints.
I solved my issue by making sure Debug was set to Local:
In my case, I was setting breakpoints in a unit that whilst open in the IDE was not part of the currently active project. Such breakpoints also show as green. IOW I was not on the right page at all.
(I discovered this after trying all of the above .)
If the project group uses packages (BPLs) ensure that none of them have any compiler warnings regarding implicitly imported units. If these exist you will only be able to step through the code via the CPU debug window.
Bit late answer but I stumbled on this problem too.
If I activated the MyPackage.bpl (bold) in the project manager with the debug configuration, then compiled it, I could see the IDE registered the debug information (blue dots on left of editor).
But when I activated my MainProject.exe (the one using MyPackage.bpl), those blue dots would disappear, indicating that the debug information is no longer present. After some head scratching, I realized that I did set up a dependency (right click on MainProject.exe -> Dependencies) on the Release configuration of MyPackage.bpl and not on the Debug configuration.
Each time I compiled MyProject.exe, it would link with the Release configuration, not the debug configuration!
So check your dependency configurations!
I had MSBuild checked under Delphi Compile (we do MS Builds). That was preventing breakpoints from working. Unchecked and it works.
By using F9 to run the app, breakpoints will work as expected. I am using XE4 and I do not know if this will "fix" prior versions of Delphi.
Since this is the best resource I found on this issue when encountering this problem with a new install of Delpi XE on a new laptop, I will just add in one more possible answer for Delphi XE.
If you are using a two monitor setup and the code editor window is on the 2nd monitor, the tooltips will not show. Works fine if the editor window is on the primary monitor. Very frustrating. May be a driver issue.
I wrote my code in D5, then I switched to D7. Things are ok, until compile. D7 appears hang and I have to killed the process. I already deleted all the DCUs and the problem persists.
Anybody had this problem before?
Thanks!
Did you try to make the compilation via the command line compiler?
I suggest you install Delphi Speed Up from http://andy.jgknet.de/blog/ide-tools/delphispeedup
You could also download the CnPack from http://www.cnpack.org/index.php?lang=en
There are some options to Set the IDE to run in CPU 0 single core.
Try to create a new project, then add your units one by one, until it freezes...
What .Net FrameWork is installed in your system?
Try this
Project|Options|Compiler Messages dialog, there's a long list of checkboxes. The last three have to do with the Dot Net Versions.Have you unchecked those last three? I think it would not work for you, or reinstall Delphi once.
I not faced such situation (D7 in Win7 )
Try: "Project/Build All Project"
And be sure that is checket switch: "Tools/Enviroment Options/Preferences/Show compiler progress".
Than tell as where compiler stops.
Debug breakpoint's works fine in all other 38 units of my system. But, in my DataModule, that have +- 10.000 lines, delphi disables then after I launch by F9/F8/F7. In any part of source that unit, even on obrigatory steps like OnCreate, SQLConnection.Active:=true, etc.
Detail: works fine until +- 20 days ago.
I'm using D7 and have all sources of components also.
Thanks
Felipe
Try doing a full build (Shift+F9). If that does not work, then what happens if you simulate a breakpoint in code with the below?
asm int 3 end;
Check for multiple copies of your source file for the datamodule. Sometimes the code you think you're running isn't the code the compiler and debugger are seeing.
Next, make sure you haven't accidentally turned off debugging in your code with {$D-} or {$DEBUGINFO OFF}. This can turn off debugging info for a single unit.
Also, make sure you've turned on Integrated Debugging in Tools|Options|Debugger Options. I know you said you could debug other places, but it can't hurt to make sure that integrated debugging didn't get accidentally turned off somehow.
I discovered this problem. It's a weird behavior in Delphi7 that limits the number of fields in interface class section, between: type TDM=class(TDataModule) and private section. I deleted some fields (DataSet Fields (+-40 fields)) and degub runs again. I add these fields again, and debug not runs. I'm sure that's a limit, because doesn't mather which component fields I deleted. I tried with several fields, from different tables too, adding, testing and deleting. It's a shame, but is true...
Thanks for your help.
I have a vague memory that debugging very large files was buggy in old D7.
Try to break you big unit in several classes and se if you can debug outside your unit.
Another option could be to turn off debuginfo in your big file except the section you want to debug. It is worth a try.
There's a blog post from Steve Trefethen, a while back, explaining some possible reasons, although if you say you can debug other units, I doubt they'll apply.
We had the same issue with a large DataModule in Delphi 5 that wouldn't let us debug it, and kind of put it down to it being too large a file to debug and Delphi not liking it. When we moved to Delphi 2007, we could debug it again. Not sure why, nothing had changed (code wise).
Felipe, is the unit that will not allow you to debug in a dll that is being moved into or out of memory? I've found when debugging dll's that if I do something in the executable that executes code in another dll or unloads the dll that the problem unit is in - Delphi will disable all breakpoints. Usually a restart of Delphi and being sure to keep a single instance of the problem unit's dll in memory is the only solution for this problem.
I doubt size is the issue, as I have a 17k line unit that I debug regularly.
